  • Publication number: 20230294741
    Abstract: A method, a system, and a non-transitory storage media for determining agent importance prediction for autonomous driving. Input features associated with agents present in an environment surrounding a vehicle are processed. Output features associated with the agents are determined based on the input features. An importance of each agent is predicted using the output features. One or more movements of the vehicle are determined based on the predicted agent importance.

  • Patent number: 9224088
    Abstract: A scenario is simulated by providing an agent that is an object in the scenario, providing a time window for the scenario that spans the farthest reachable past time and the farthest reachable future time with respect to a present time for the agent and/or at least one player that interacts with the simulated scenario, providing at least one event that represents a change in at least one attribute of the agent, and updating a state of the scenario by applying the at least one event to the agent within the time window.

  • Publication number: 20140171793
    Abstract: A method for detecting a needle, the method comprises arranging an ultrasound probe such that it scans an area covering a needle inserted into a tissue and nearby tissue around the needle, collecting a plurality of ultrasound frames associated with motion of the nearby tissue, determining movement information of the nearby tissue, post-processing the movement information of the nearby tissue to determine a position of the needle, and outputting information relating to the position of the needle.

  • Publication number: 20070167802
    Abstract: A method for correcting beamforming time delay in an ultrasound system is provided. The method comprises transmitting a beam of ultrasound energy into an object with a transmit beamforming time delay. The method further comprises receiving a plurality of echo signals with a receive beamforming time delay and estimating beamforming time delay errors for each echo signal and each imaging direction. The method further comprises correcting the transmit and receive beamforming time delays and generating an ultrasound image of the object using the corrected transmission and reception beamforming time delays.

  • Publication number: 20050237858
    Abstract: A reconfigurable linear array of sensors (e.g., optical, thermal, pressure, ultrasonic). The reconfigurability allows the size and spacing of the sensor elements to be a function of the distance from the beam center. This feature improves performance for imaging systems having a limited channel count. The improved performance, for applications in which multiple transmit focal zones are employed, arises from the ability to adjust the aperture for a particular depth.

  • Publication number: 20050096546
    Abstract: The reconfigurable ultrasound array disclosed herein is one that allows groups of subelements to be connected together dynamically so that the shape of the resulting element can be made to match the shape of the wave front. This can lead to improved performance and/or reduced channel count. Reconfigurability can be achieved using a switching network. A methodology and an algorithm are disclosed that allows the performance of this switching network to be improved by properly choosing the configuration of the switching network.
